DIRECTION-INDICATOR FOR AUTOJTEHIGLESV Specification of Letters Patent.

Patented Dec. 27, 1921.

Application fi1ed June 25, 1920. Serial No. 391,589.

To aZZ whom Mindy concern:

Be it known that 1, Franc s HENRY Renn- Lnrr, a citizen oi the United residing at l l est "llhambra, in the county of Los ringeles and State of California, have invented new and useful improvements in Dimotion-Indicators :lor Auto-Vehicles, of whichthe following is specification.

l /l invention is animproved direction in dicato-r for auto vehicles.

The main object of my invention is to provide a direction indicator for auto vehicles embodying three sets of semaphore arms mounted in a suitable housing, each set including a pair oi arms mounted respectively on opposite sides of the vehicle to swing vertically, and independent means for operating each pair of the arms to swing them to diflerent relative positions; one pair of arms being designed to signal Left, another pair to signal Right, and the third pair to signal Stop.

(lthcr objects will appear hereinafter.

My invention consists in the features of construction, combination oi el ments, and arrangement or parts hereinafter described and Jointed out in the claims.

lily invention is illustrated in the annexed drawing forming a part or this specification, in which:

Figure 1 is a vertical section oi my direction indicator taken on line 11 of Fig. 2 showing the pair ojt' arms for signaling Left, said arms being shown in full lines in their normal position, and in dotted lines in signaling position.

Fig. 2 is a horizontal section of my direction indicator taken on line 2-2 of Fig. 1.

Fig. 3 is a section on line 33 of Fig. 2 showing the arms for signaling Right as disposed in their signaling position.

Fig. 4c is a view in section as seen on the line 4l.lof Fig. 2 showing the arms for signaling Stop in their signaling position.

Fig. 5 is a detail section on line 5-5 of Fig. 2 showing the manner of illuminating the arms by electric lamps when in their signaling position, controlled by the arm operating mechanism.

An important feature of the invention resides in a means whereby on movement of the operating levers controlling each pair of arms, at corresponding distances the arms will be caused to move to various positions.

In the drawing 1 indicates a U-shaped housing formed with a horizontal member 2, and upstanding members 3 and 4, there being vertical slots 5 in the outer sidewall or"- said arms; i i-series of telescoping shafts 6, 7, and 8 are journaled in the casing member 2 midway betwee the arms 3 and i, which are fitted with the handles 9, and 11 respectively outside said member. Shaft 6 carries fined wheels 12 and different diameters; shaft carries wheels i l and 15 oi different diameters, and shaft- 8 carries wheels 16 and 17 of correspond n diameters, all of said wheels being loca within the" housing member 2. Pivoted signal arms 18 and 19 forindicating Left are mounted in the housing members 3 and 4i with wheels 20 and 21 of diameters corresponding to each other and to the wheels 13, and passing around the wheels 12 and 19 and aifixed thereto is a cross cable 22, and passing around wheels 13 and 20 and aflixed thereto is a cable 23. Depression of the Left lever 9 will operate through the cables 22 and 23 to swing the arm 18 through a slot 5 in the housing member 3 into horizontal position and the arm 22 through a slot 5 in the housing member l to an inclined position as shown in Fig. l. The signal arms 24: and 25 for signaling- Right are mounted on wheels 26 and 24' of corresponding diameter in the housing arms 3 and l, and extending between the wheels 15 and 27 is a cross cable 28, and between the wheels ll and26 a cable 29. Depression of the Right lever 10 will act through the cable 28 and-29 to rock the arm 25 through a slot 5 in the housing member l to horizontal position and the arm 24 through a slot 5 in the housing member 3 to an inclined position as shown in Fig. 3.

The signal arms 30 and 31 for indicating Stop are mounted in the housing members 3 and 4 on wheels 32 and 33 of correspond-- ing diameter but of a diameter less than that of wheels 16 and 17, and extending between the wheels 16 and 33 is a cross cable at and between the wheels 17 and 32a cable 35. On depression or the Stop lever ii the arms 30 and 31 will be swung corre sponding distances through two slots 5 respectively into downwardly inclined position shown in Fig. l.

On moving the arms 9, l0, and 11 from their normalpositions spring press switches 9, 10, and 11 will operate to close their electrical circuits leadmg through lamps 36 arranged on top of the housing arms 3 and l above the signal arms, to direct light on the arms when they are in their signaling position; the contact members being held out 7 of their circuit closing position when the 1n'th'e1r normal positlon as handles ar shown in Fig. 5.

Clips 39; 40, and 41 hold the handles 9, 10 and 11 and the signal arms actuated thereby in their normal non-signaling position and in such position said handles hold the switches 9, 10, and 11 open breaking the circuit of lamps 26.

, While I have shown and described a specific embodiment of my invention, I do not limit myself to the exact details of construction shown, but may resort to such changes and modifications as occasion may require and as may come within the scope or the appended claims, without departing irom'the spirit of my invention. o

I claim: a

1. In a direction indicator for auto ve- -hicles, three pairs of signaling arms marked respectively Left, Right, and

Sto the arms of each air bein ar a P a:

ranged respectively at the sides of the ve-- hicle, means for swinging the .Left? arm at the left side of the vehicle horizontally and simultaneously swinging the Left arm at the right side of the vehicle at an angle, means for swinging the Right arm at the right side of the vehicle horizontally and simultaneously swinging the Right arm at the left side or" the vehicle at an angle, and means for swinging both Stop arms downwardly at an angle.

2. In a direction indicatorfor vehicles, a pair of signaling arms arranged on opposite sides of the vehicle and normally disposed in parallel relation to each other and means for swinging said arms simultaneously at different speeds relative to each other whereby one of said arms will be disposed at an angle to the horizontal when the other is positioned horizontally.
